He is the caring brother to Mario. After Mario's beat up by Roxx, he sent a Coffee Mushroom to Mario to save him. He takes responsibility, and when realizing only 1 Coffee Mushroom existed, he made sure to clone more. He got a little action to Roxx. He socked him far into the sky. He hates Toad more than Mario does. Anytime he can talk trash about him he will. He has to hide from Ian, cause he's a target. He is also able to enter Eggbert's reality. In the reality, his neck is very weird. His life isn't great there however. He also secretly doesn't like Mario, as he had a good dream about kicking his behind.
He has a bald spot on his head. So, he always tries to get products to help with it. Sadly, alot cost too many. He also used to have 2 kidney stones, which were exposed by Benjamin Frankinstein on a video.
Never a good idea to call him Loogini. Eggbert by accident, said it. Eggbert then got attacked and beat up. It happened twice, as Eggbert went to tell Owl. There's a theory that he is gay. He one time was watching some guy in his underwear dancing and twerking, and Mario caught him. Luigi said it isn't what it looks like. The video was loud so Mario told him to help search for Obunga.
